Standalone ZODB + BTree question

[Van Gale]

Can anyone point me in the right direction for using OOBtree with ZODB?

I've been able to figure out FileStorage and DbmStorage easy enough from the
docs, and I can create and use an OOBTree... I just can't seem to tie it
into persistent storage.

The BTree unittest *seem* to just be running tests on in memory btrees, so I
haven't been able to use them as an example.
